<!--
|
||
Enables [the scheduler's _queueing hints_ enhancement](https://github.com/kubernetes/enhancements/blob/master/keps/sig-scheduling/4247-queueinghint/README.md),
|
||
which benefits to reduce the useless requeueing.
|
||
The scheduler retries scheduling pods if something changes in the cluster that could make the pod scheduled.
|
||
Queueing hints are internal signals that allow the scheduler to filter the changes in the cluster
|
||
that are relevant to the unscheduled pod, based on previous scheduling attempts.
|
||
-->
|
||
启用[调度器的**排队提示**增强功能](https://github.com/kubernetes/enhancements/blob/master/keps/sig-scheduling/4247-queueinghint/README.md)，
|
||
有助于减少无效的重新排队。
|
||
调度器会在集群中发生可能导致 Pod 被重新调度的变化时，尝试重新进行 Pod 的调度。
|
||
排队提示是一些内部信号，
|
||
用于帮助调度器基于先前的调度尝试来筛选集群中与未调度的 Pod 相关的变化。
